APPARATUS FOR COOLING GAS-ENGINE CYLINDERS.

SPECIFICATION forming part of Letters Patent No. 624,827, dated May 9, 1899.

Application filed October 16, 1897. $erial No. 655,454. (No model.)

To all whom it may concern:

Be it known that 1, JOHN W. LAMBERT, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Apparatus for Cooling Engine-Cylinders, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a side elevation of the apparatus, parts being broken away to more fully show its construction; and Fig. 2 is a vertical 1 sectional view of a portion of the apparatus.

This invention relates to an apparatus for cooling gas-engine cylinders by causing a circulation of water around the same, said Water after it leaves the water-jacket su rrou'nding the cylinder being cooled by a suitable medium and then returned to the waterjacket.

The object of the invention is to provide an apparatus which will cause a constant circulation of the water and secure an effective cooling of the heated water without causing a too rapid evaporation thereof.

Referring to the various parts by numerals, 1 designates a gas-engine cylinder which is provided with a water-jacket of any desired construction. water-jacket upward to a tank 2 is a pipe 8, through which the water which has passed through the jacket and become heated passes up to the tank. This tank is supported at a suitable height above the cylinder, and the pipe 3 enters through the bottom'the-reof, its end extending vertically to a point a suitable distance below the normal water-level in the tank. Surrounding a portion of this pipe within the tank and extending above its upper end is the upper vertical exit end of an air-blast pipe 4, whose inlet end is extended outside of the tank, said pipe at a point between its inlet and its outlet end being carried above the water-level in the tank, as at 10, to form a trap to prevent the Water flowing out through said blast-pipe when the blast is reduced. Surrounding the exit end of a the blast-pipe is a cylindrical hood 5, which is somewhat larger in diameter than the blastpipe, so that a space is formed between the pipe and the hood. The lower end of this Leading from the top of the hood is open and extends below the end of the blast-pipe, and its upper end is closed with a hollow inverted conical top 6. The apex of the conical deflector is over the center of the open end of the blast-pipe and its base is equal in diameter to the hood, so that an annular V-shaped recess is formed at the top of the hood. Below the lower open end of this hood is mounted a circular deflector 7, whose upper surface inclines downward and outward and whose inner edge fits tightly around the blast-pipe. The outer edgeof the deflector -extends out beyond the outer'circumference of the hood 5, so that the comas they pass down out of the hood. The parts may be supported as desired, a simple manner being shown in the drawings, wherein the deflector is supported on the blast-pipe, and the hood is carried by the deflector by means of short legs 8. Connected to the inlet end of the blast-pipe is a blower 9, which is connected by a suitable belt or driving means to the driving-pulley of the gas-engine or other source of power. the tank flows through a pipe 11 to the lower portion of the water-jacket around the engine-cylinder.

In operation the tank is filled with water to a point somewhat above the end of the inlet-pipe 3. Whenever the engine isin operation, the fan 9 is running and is forcing a blast of air through pipe This blast of air at the beginning of the operation throws the water which may have accumulated in said pipe beyond the trap 10 up into the hood 5 and over the cone 6 and into the V-shaped recess, formed by the cone and the vertical wall of the hood. From that point the commingled water and air pass down to the deflector 7 and then out into the tank, the air passing out at the top thereof. When. the water in the blast-pipe has been blown out into the tank, the level of the water in. the

tank will have been thereby made higher than that in pipe 3, and because of this difference in the level of the water in the tank and in the pipe the water will be gentlyforcedout of the pipe 3. When this water flowing out Water from the bottom of of pipe 3 meets the upward-rushingair in the blast-pipe, it is carried forcibly up into the hood and sprayed over the cone and walls of the hood, being cooled thereby. By thus constantly lifting the waterout of the blastpipe into the tank the water in the tank is maintained higher than that in pipe 3, and a constant flow of water is thereby kept up through the jacket around the cylinder and up through pipe 3. As the blast of cool air rushes in through pipe at it first surrounds the upper part of water-inlet pipe 3 and tends to cool it. It then rushes up around said pipe and carries the inflowin g water into the hood, where the water is cooled by commingling with the cool air and coming in contact with the walls of the hood. A greater portion of the steam or vapor from the hot water will be condensed by the cool air, the walls of the cone and hood, and the deflector; so that the water lost by evaporation will be reduced to a very small percentage. It will be observed, therefore, that the hood or an equivalent device is an essential feature in that it receives the impact of thespray and separates the water from the air and returns it to the tank while permitting the air to escape laden with but a minimum of vapor. It will thus be seen that a constant positive circulation of water is maintained through the Water-jacket and that the blast of air which causes this circulation cools the water by commingling the water and spraying it. In this way the use of a common pump for maintaining a positive and ample circulation is avoided and the water is quickly and materially reduced in teinperature, rendering it necessary to keep but a small supply of water in the tank, which is a great desideratum in many cases.

It is obvious that it is not absolutely essential that the water-level be above the open end of pipe 3, since the blast of air will tend to create a partial vacuum at the end of said pipe, which will cause the atmospheric pressure to force the heated water up through said pipe, the water as it issues from the end of the pipe being taken up bodily by the blast and thrown forcibly into the hood.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
